Crisp start, warming up later

Runners will face a cool start at 37°F, gradually warming to 54°F by the finish. Wind will be a factor, with gusts up to 20 mph creating headwinds during challenging climbs, particularly around miles 10 to 16. Runners should consider adjusting their pacing strategy on the climbs and ensure proper hydration as temperatures rise, while also dressing in layers for the early chill.
